Fucking like minks until the fur has become matted with saliva, sweat, and sexual juices, lying in a pile, unable to even move.

Talk about that.

Happens and has happened,but more like rutting weasels.Most memorable was with a zoo biologist I caught a ride with into DC,She offered to give me a backrub,and something about her scent set me off. Literally hours later,having stayed hard thru a half dozen orgasm myself(no chemicals other than our own juices),and unknown number for her,we both flopped down on her bed in a puddle of mingled fluids and passed out,not to awake for almost the whole day.
